To all whom t may concern:

Be it known 'that I, JOHN Ii.,y kGriswold),

al citizen of the United States', residing at Dodge Center., in the' county of Dodge and State `of Minnesota, have invented. certain new and ,usefulv Improvements in Pig- Guards; and I do herebydeclare the followA ing to be a full, clear, and exact description of the invention, such as will enable others skilled ign the art .to which it appertains to make and use the same.

Myinvention relates to improvements in pig guards; and, to this yend, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. 4 Y

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views. y Referring to the drawings,.Figure l is a view, partly in elevationand partly in section, with'some parts illustrated diagrammatically, and some parts shown in different positions, by means of broken lines; Fig. 2 is a front elevation of the improved guard, some parts being broken away; Fig. 3 is a fragmentary detail view, with some parts sectioned on the line m3 w3 of Fig. 2, on an enlarged scale; and Fig. l is a perspective view of one of the wall brackets on an en larged scale. l

The numerals l and 2 indicate, respectively, one of the walls and the door of'a hog house. As shown, the pig guard is in the form of a horizontal tubular rail 3, normally held by a pair of arms i spaced outward of the front 1 and above the floor 2. The arms L are secured,"at one of their ends, to the wall 1 by a ,pair Vof wall brackets 5 and have, at their other'or free ends, integrally formed hubs 6 through which are telescoped the guard rails'f. VSet screws 7 hold the guard rail 3 and the hub 6 against both rotary and endwise movement.

The wall brackets. 5 arci-shape in cross section and in each iange thereof are countersunk holes through which screws may be passed for securing said. brackets `either to the lside or end walls of the hog house. Projecting from one of the flanges of each wall bracket 5, is a pivot stud 8 and projecting from the' other liange thereof, is a lug 9. These lugs 9 extend' trans` versely of the studs 8 and are located out- Ward therefrom,l as best shownin Fig.-4.

In swing'ng the arms 4 from the ,full line to the dotted line position, as shown in Fig. l, the slot and pin cor-.nec--- "tions 8 and l0 permita slight endwise movement of said arms. This movement of the arms 4 carries their pivoted ends a suicient distancev below the studs 8 to prevent pivotal Vmovement thereof by the engagement of the armed-'with the wall brackets "i,

The wall brackets 5 are so located as to support the guard rail 3 a sucient distance above the floor 2 to permit the little pigs to pass thereunder, but not the large or full grown ones. The stop fingers l1 hold the guard rail 3 outward from Athe wall l a distance sufficient to permit the little pigs to lie on the floor between the guard rail 3 and wall l, orto freely move about therebetween.` Obviously, the guard. rail 8 prevents the large or full grown pies from lying on the little ones, crowding the same against the wall or otherwise hurt-ing the same.

The combination with the Wall and ioorof a hog house, of a pair of brackets secured to the Wall, a pair of arms pivoted to the bracket for vertical swinging movement, a guard rail carried at the free ends of the arms; and held thereby above the floor, a s top finger on each of the arms loselyengaging the vWall for holding the guard rail spaced apart therefrom, and means for holding the arms raised. 1

The, combination with the Wall and floor of a hog house, of a pair of brackets secured to the Wall, a pair of arms secured to the brackets by slot and pin connections, a guard rail Icarried at the free ends of the arms and held lthereby above the floor, a stop linger in each of the arms engageable with the Wall for holding the guard. rail spaced apart therefrom, said arms' arranged, when raised, to interlock with the brackets by an end wise sliding nfovement.
